Abstract

The invention discloses a detection device based on an underwater low-frequency electric field and an underwater detection positioning method. The device comprises a bearing device, a driving cabin body and a control cabin body. A generating electrode and a plurality of receiving electrodes are arranged below a bearing device. A structure that a plurality of sliding grooves are formed in the samecircumference of the transmission bevel gear in a circumferential array manner is utilized. A transmission lead screw is arranged in the sliding groove. A driven bevel gear is fixed at one end of thetransmission lead screw. The driven bevel gear is meshed with the transmission bevel gear. The transmission lead screw is sleeved with a receiving electrode fixing sliding block. The distances from the receiving electrodes to the generating electrodes are equal. A one-to-many array electrode arrangement form is adopted. Real-time acquisition of electric field signals in all directions in a detection area is realized by means of a generating electrode and a plurality of receiving electrodes which are arranged at the central position. Compared with the arrangement form of a single sensor, the electric field signals acquired are more accurate, the acquisition efficiency of the signals is remarkably improved, and the position of the target object between the generation electrode and the plurality of receiving electrodes can be rapidly and accurately acquired.

Description

technical field [0001] The invention belongs to the technical field of underwater detection, and in particular relates to a detection device based on an underwater low-frequency electric field and an underwater detection and positioning method. Background technique [0002] The rapid detection and accurate identification of underwater target objects has become a research hotspot in the field of modern national defense and ocean engineering. According to different detection methods, there are currently two traditional underwater detection methods, namely: underwater acoustic detection and underwater optical detection. The basic principle of underwater acoustic detection is to transmit ultrasonic waves through acoustic equipment, and then by receiving the scattered echoes generated by the sound waves on the surface of the object, according to the size of the scattering intensity and with the help of physical phenomena such as the Doppler effect of the sound waves, the contour ...
